Neuraxial analgesia in labour and the foetus.

Providing pain relief during labour is a fundamental human right and can benefit both mother and foetus. Epidural analgesia remains the 'gold standard', providing excellent pain relief, as well as the facility to convert to anaesthesia should operative intervention be required. While maternal well-being remains the primary focus, epidural analgesia may also have implications for the foetus. Data from meta-analyses finds that epidural compared with systemic opioids in labour is associated with reduced neonatal respiratory depression. Clinically relevant neonatal outcomes such as Apgar score <7 at 5 min, neonatal resuscitation and need for admission to a neonatal unit are reassuring, with the benefits of epidural analgesia for both mother and neonate outweighing any potential risks. Recent concerns regarding an association of epidural with the development of autism spectrum disorder in childhood appear to be unfounded, with several large observational studies refuting this association. This review discusses the evidence relating to maternal neuraxial analgesia in labour, implications for the foetus in utero, and childhood outcomes both in the immediate peripartum period and longer term.
